Hi! Good evening. I am Dr Shareef answering your query. If I were your doctor, in this case I would have advised you for a routine stool test for ova and cyst, a urine test (routine/microscopic/culture and sensitivity), and treat these if positive. If inconclusive and non relief of symptoms, I would advise you for an ultrasound of abdomen, and an X-ray chest to rule out any stone in the left sided urinary tract and any infective lesion in the chest. I would avoid advising you a laxative without getting into a diagnosis. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
